(d) Lewis dot structure of SF6 is
Central atom, S has total 12 electrons. So, it does not obey octet rule.Lewis dot structure of PCl5 is central atom, P has total 10 electrons. So, it also does not obey octet rule.Lewis dot structure of XeF2 is central atom, Xe has total 10 electrons. So, it does not obey octet rule.
Hence, the set of molecules that does not obey octet rule is SF6,PCl5 and XeF2.
